Y. 1 CULTIVATOR.

Patented Aug. 15, 1911. Serial No. 516,626.

To all whom it may concern:

Be it known that I, LEWIS E. VATERMAN, a citizen of-the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certainrnew and useful Improvements in Cultivators, of which the following is a specification.

The object of this invention is to construct a cultivator in which a supporting wheel and one set of shovels oscillate together in a horizontal plane.

In the accompanying drawings, Figure 1 is a side elevation of my improved cultivator. Fig. 2 is a plan view of one side of the cultivator, the opposite side being a duplicate thereof. Fig. 3 is a rear elevation of one side of the cultivator. F ig. 4 is a. plan view of one supporting wheel and one set ofa shovels.

As both sides of the cultivator are the same, and are independently connected to the main frame, the illustration and description of one side will be given.

The main frame comprises the tongue 1, a rear cross-bar 2 and braces 3 pivotally connecting this cross-bar with the tongue by the bolt 4. A seat support 5 has a connection with the braces 3 and rests upon the cross-bar 2, a seat 6 is supported by the seat support 5,

To the end of the cross-bar 2y is secured a vertically arranged tubular bracket 7. An upright rock shaft 8 is located in the bracket, abar 9 extends across the brace bars 3. A quadrant 10 having two sets of teeth, as shown in Figs. 2 and 3 is pivotally connected to the bar 9, and is fixedly connected to the upper end of the rock shaft 8. A nut 11 is turned in connection with the upper end of the rock shaft. The lower end of this rod 8 is formed with an eye 12. A footlever 13 is fixedly connected with the lower portion of the rock shaft 8 by the setscrew 14. This foot lever extends inward and is located with relation to the seat so that the driver can reach it.

A cranked axle is composed yof the mainV section 15, the lateral bends 16 and 17 and the sections 18 and 19 extending parallel with the main section. A supporting wheelr 20 is mounted on the main section, and the eye 12 of the rock shaft 8 receives the main section and is located near the supporting wheel. The wheels 20, through the rock shaft 8, and brackets 7 serves to support the main frame including the drivers seat. The sections 18 and 19 of the cranked axle support a frame to which the shovels are conn ected. This frame comprises the two sections 21 and 22 pivotally connected by the bolt 23. The section 21 is pivotally mounted on the section18 of the cranked axle, and the section 22 is pivotally mounted on the section 19 of the cranked axle. The forward end of the section 21 has an upturned extension 24 provided with holes 25. A rod 26 is held in connection with the extension 24 by the eye bolts 27 in a manner to permitthe rod to oscillate. The upper end of the rod 26 has a4 crank portion 28, and the lower end has a crank-portion 29. A link 30 has one end pivotally connected to the crank portion 29 of the rod 26. The otherl end of this link 30 is pivotally connected to the forward end of the section 22 by the bolt 31. Shovel standards 32 are connected to the section 22 to which shovels 33 are secured. A shovel standard 34 is connected to the branch 21 to which a shovel 35 is secured. A draft attachment 36 has a connection with the link 30 and is adjustable lengthwise thereof by the holes 37.

A hand-lever 38 has a pivotal connection with one section of the toothed quadrant 10, and is provided with a dog engagement therewith. A foot lever 39 has a pivotal connection with the bracket 7 on the bolt 40, and has an inwardly turned foot rest. A rocking lever 41 is pivoted about midway its ends to ther toothed quadrant 10. One end of this rocking lever has a connection with the foot lever by the link 42, and the other end of this rocking lever is connected to the extension 24 of the section 21, by the bolt 43. The hand lever may engage the stop 44 carried by the rocking lever 41 for the purpose of operating said lever 41 or holding it in different positions. A hand lever 45 has a pivotal connection with the other section of the toothed quadrant 10 and is provided with the usual dog engagement with the toothed quadrant of said section. A link 46 connects the hand lever 45 with the upper crank arm 28 extending from the rod 26.

A toothed quadrant 47 is supported by the tongue 1. A hand lever 48 has a pivotal connection with the toothed quadrant 47.

6 5 each "axle The forward ends of the brace bars 3 are connected by the bar 49, and a link 50 connects the hand lever 48 with the fo-rward end of one of the brace bars 3.

By means of the hand lever 48 the forward ends of the brace bars 3 can be elevated or depressed which will rock that part of the cultivator in rear of the pivotal bolt 4 to level the frames carried by the supporting wheels. By means of the hand lever 3S, or the foot lever 39 or both, the sections 21 and 22 can be raised and lowered which will rock the cranked axle in the supporting` wheel 20. By means of the hand-lever 45, the rod 2G will be oscillated which will narrow or widen the distance between the sections 21 and 22, consequently the distance between the shovels will be changed. The section 22 will slide on the section 19 of the cranked axle, a suitable boxing being provided that will permit such movement. By means of the foot lever 13 the rock shaft S is turned which will turn the shovel supports and the wheel 20, and will also move the bar 9 which extends across the brace bars 3 of the main frame, and connects with the toothed quadrant on the other side of the frame, thereby moving both supporting wheels and both sets of shovel supports in unison.
